Evelyn and I also spent some time in the Potions Garden, and I managed to, um, filch a few slips of some of the rarer ingredients and stash them in a botanist pocket. It was all overgrown, and no one else was there, so I took the risk. The spells on the pocket kept them in good condition all day, and I've set them in rooting solution tonight. I hope to get about ten plants if all goes well, and we can propagate from there. I'll send you both a list of the ones I've definitely identified, but one or two weren't labeled, and I think you should classify them.
